Organ size and pattern results from the integration of two positional information systems. One global, encoded by the Hox genes, links organ type with position along the main body axis. Within specific organs, local information is conveyed by signaling molecules that regulate organ growth and pattern. The mesothoracic (T2) wing and the metathoracic (T3) haltere of Drosophila represent a paradigmatic example of this coordination. The Hox gene Ultrabithorax (Ubx), expressed in the developing T3, selects haltere identity by, among other processes, modulating the production and signaling efficiency of Dpp, a BMP2-like molecule that acts as a major regulator of size and pattern...

Chonopeltis Thiele, 1900 presently comprises 14 species, it is endemic to Africa and its species show a high degree of host-specificity towards fish families and in some cases, individual fish species. Chonopeltis meridionalis Fryer, 1964 was originally described from Labeo rosae Steindachner collected in the River Nuanetsi in Rhodesia, now Zimbabwe, Limpopo River System. At the time of description C. meridionalis was the most southerly species of the genus. Chonopeltis victori Avenant-Oldewage, 1991 was described from the River Olifants, Mpumalanga, South Africa, which also forms part of the Limpopo River System...

Understanding the driving forces behind the shifts in the ecological balance of the oral microbiota will become essential for the future management and treatment of periodontitis. As the use of competitive approaches for modulating bacterial outgrowth is unexplored in the oral ecosystem, our study aimed to investigate both the associations among groups of functional compounds and the impact of individual substrates on selected members of the oral microbiome. We employed the Phenotype Microarray high-throughput technology to analyse the microbial cellular phenotypes of 15 oral bacteria...

Lignin is a biomass-derived aromatic polymer that has been identified as a potential renewable source of aromatic chemicals and other valuable compounds. The valorization of lignin, however, represents a great challenge due to its high inherent functionalization, what compromises the identification of chemical routes for its selective depolymerization. In this work, an in vitro biocatalytic depolymerization process is presented, that was applied to lignin samples obtained from beech wood through OrganoCat pretreatment, resulting in a mixture of lignin-derived aromatic monomers...

INTRODUCTION: The upregulation of PD-L1 is found in many cancers and contributes to the evasion of the host's immune defence. In malignant pleural mesothelioma (MPM), PD-L1 expression is associated with non-epithelioid histological subtype and poor prognosis, but the pathways involved in the control of PD-L1 expression in MPM are poorly understood. To address one possible means of PD-L1 regulation we investigated the relationship between dysregulated microRNA levels and PD-L1 expression...

Visceral leishmaniasis is a neglected disease caused by Leishmania protozoa parasites transmitted by infected sand fly vectors. This disease represents the second in mortality among tropical infections and is associated to a profound immunosuppression state of the host. The hallmark of this infection-induced host immunodeviation is the characteristic high levels of the regulatory interleukin-10 (IL-10) cytokine. In the present study, we investigated the role of B-1 cells in the maintenance of splenic IL-10 levels that could interfere with resistance to parasite infection...

BACKGROUND: Pluripotent stem cells, including induced pluripotent stem cells (iPSCs), have the capacity to differentiate towards all three germ layers and have been highlighted as an attractive cell source for the field of regenerative medicine. Thus, stable expression of therapeutic transgenes in iPSCs, as well as thereof derived progeny of hematopoietic lineage, may lay the foundation for innovative cell replacement therapies. METHODS: We have utilized human iPSC lines genetically modified by lentiviral vector technology or targeted integration of reporter genes to evaluate transgene expression during hematopoietic specification and differentiation towards macrophages...

Ovarian vein thrombosis (OVT) is a rare medical disorder most often diagnosed in the peripartum period and maybe associated with other risk factors for thrombosis. Rarely, OVT is considered idiopathic. It occurs in the right ovarian vein alone in two-thirds of patients. In this report, we present a case of idiopathic and bilateral OVT in a 35-year-old woman who presented with 2-day history of left flank pain. Duplex ultrasound imaging and computed tomography confirmed the diagnosis. Oral anticoagulation achieved a favorable outcome...

In the present work two subclasses of the human antibody Immunoglobulin G (IgG) have been investigated by Small-Angle X-ray Scattering under high hydrostatic pressures up to 5kbar. It is shown that IgG adopts a symmetric T-shape in solution which differs significantly from available crystal structures. Moreover, high-pressure experiments verify the high stability of the IgG molecule. It is not unfolded by hydrostatic pressures of up to 5kbar but a slight increase of the radius of gyration was observed at elevated pressures...

Spongy degeneration with cerebellar ataxia (SDCA) is a genetically heterogeneous neurodegenerative disorder with autosomal recessive inheritance in Malinois dogs, one of the four varieties of the Belgian Shepherd breed. Using a combined linkage and homozygosity mapping approach we identified a ~10.6 Mb critical interval on chromosome 5 in a Malinois family with four puppies affected by cerebellar dysfunction. Visual inspection of the 10.6 Mb interval in whole genome sequencing data from one affected puppy revealed a 227 bp SINE insertion into the ATP1B2 gene encoding the β2 subunit of the Na(+)/K(+)-ATPase holoenzyme (ATP1B2:c...

Previously we have shown that low temperature stress in Arabidopsis causes defects in microtubule organization and cytokinesis in male meiocytes, which leads to the formation of diploid pollen. Because cytokinin (CK) mediates multiple physiological responses to cold stress, we investigated whether CK signaling is involved in cold-induced diploid pollen formation. To this end, we monitored male sporogenesis in a series of mutants defective in CK metabolism and signalling. Arabidopsis plants with altered CK homeostasis, i...
